I have one of those but it's faster for me to use my RCBS hand seater with the 100 Primer holder. I've had and have several priming tools but find the RCBS the best and most comfortable.

I got the RCBS tool shortly after they came out. My experience with it was that it was designed for someone with bear paws for hands. RCBS confirmed that the designer was a really big guy. Unless they have a redesigned “Gen 2”, I would not suggest buying one unless you have an opportunity to try it out.
